Hi,

I have the factory recovery image USB with me which I created from Dell DataSafe, am I ready to format my machine, or do I need to consider any thing else?

Dell Datasafe had issues which were resolved with Dell Backup and Recovery... You will need to restore your factory image on your new HDD then update to the last version of Dell Backup and Recovery, then recreate the Recovery USB. After you have done that you should reinstall the OS from it and it should occupy your entire HDD.

Hi Philip,

Thnks for the info. Currently my disk mgmt is showing the below details:-

Disk0 Basic 465.76 GB Online:- -

(a) 125 MB Healthy (OEM Partition).

(b) 9.42 GB Healthy (System, Active, Primary Partition).

(c)  OS (C:)  60 GB NTFS Healthy (Boot, Page File, Crash Dump, Primary Partition)

(d) 396.22 GB Unallocated.

The concern is I am unable to allocate more disk space to my C: drive. When i try to allocate it says "You cannot create a new volume in this un-allocated space because the disk already contains the maximum number of partitions."

I also tried from a third party tool, however it reflects 466 GB Fixed disk under which it reflects NO NAME (1:) 125 MB as primary FAT32, not ready (2:) as 9.42 GB primary unknown, OS (C:) 60 GB Primary NTFS, 1.00 MB Extended Partition. So nowwhere its showing me that 396.22 GB unalloacted space through this tool.

Please suggest as I am unable to increase space on my c drive.

Regards,

Sushant

As I said update to Dell Backup and Recovery then make the Recovery USB again. Then attempt OS reinstallation with the USB.

Hi, I downloaded the backup and recovery tool, then while installing it, I removed the Dell local backup tool(the old one), but then it stops and installation never completes.please suggest

Formatting and installing a new copy of Windows is a great solution for many PC issues, but it takes time and all of your program data and settings are lost. You have to re-install all your drivers and software and configure them properly, so in this post, I will tell you the main reason for the expansion of formatting.
